Steps required NOT to support iphone3g

I have created a universal app for iphone. My questions is what are the steps necessary to NOT support iphone3g and non retina device. What are the settings in xCode and iTunes Connect that I need to adjust to pass review process?

Solution

The last iOS version that the iPhone 3G supported was 4.2.1. If you set your "iOS Deployment Target" to a value above 4.2.1 (Example: 5.0), this would make it so the app would not run on those devices. The iOS Deployment Target setting is located under the "Build Settings" tab.

Be aware that the iPhone 3GS is non-retina and would require a value higher than 6.1.3 to exclude it.
